Abstract

The process involves blanching observation received on reception sensors in order of four, for orthonormalizing directional vector of sources in quadric-covariance matrices of processed observations. The quadric-covariance matrices are joined to identify spatial signatures of the source. The processed observations corresponding to the quadric-covariance matrices are temporarily realized by a predetermined equation.
